为什么 gulp-uglify breaks backendless？

Question

我真的不知道，我应该给你看哪部分代码。

我有一个webApp（reactJs、flux、react-router、nodejs+express server）；它工作正常，直到我 uglify main.js 文件。

这里"search"通过后端数据库(http://backendless.com/documentation/data/js/data_search_and_query.htm)

 var dataQuery = {
        condition: conditions,
        options: {
          pageSize: 18,
          relationsDepth: 1
        }
      }

如果我不在我的构建中使用 gulp uglify，它工作正常。如果我确实使用 uglify，我会收到此错误： GET https://api.backendless.com/v1/data/t?pageSize=18&relationsDepth=1 404（未找到）

为什么会这样？

UPD#1 Gulpfile.js:

var gulp = require('gulp');
var browserify = require('gulp-browserify');
var concat = require('gulp-concat');
var uglify = require('gulp-uglify');
var uglifycss = require('gulp-uglifycss');




gulp.task('browserify', function() {
    gulp.src('src/js/main.js')
      .pipe(browserify({transform: 'reactify'}))
      .pipe(concat('main.js'))
      .pipe(gulp.dest('dist/js'));
});

gulp.task('uglifyjs', function() {
  gulp.src('dist/js/main.js')
      .pipe(uglify())
      .pipe(gulp.dest('dist/js')) 
});
gulp.task('copy', function() {
    gulp.src('src/index.html')
      .pipe(gulp.dest('dist'));
    gulp.src('src/assets/**/*.*')
      .pipe(gulp.dest('dist/assets'));
});

gulp.task('default',['browserify', 'copy']);

gulp.task('watch', function() {
    gulp.watch('src/**/*.*', ['default']);
});

gulp.task('js', function () {
  gulp.src('src/jsLibs/*.js')
    .pipe(concat('scripts.js'))
    .pipe(uglify())
    .pipe(gulp.dest('dist/js'))
})

gulp.task('css', function () {
  gulp.src('src/css/*.css')
    .pipe(concat('styles.css'))
    .pipe(uglifycss())
    .pipe(gulp.dest('dist/css'))
})

Answer 1

你能给我 .js 文件中的代码吗，你从哪里进行查询以查找数据对象。我认为您确实在另一个 class 中进行搜索。

Answer 2

GET https://api.backendless.com/v1/data/t?pageSize=18&relationsDepth=1 404 (Not Found)

此请求发送至名为 t 的 table。我很确定你的 table 名字不是 t.

Answer 3

正如我们在 support forum 上的回答：

Our JS SDK forms the url from the name of your constructor-function, thus if you rename it - the request will query another table, and for now there is no way to change this logic from your code.

So you're looking in the right direction: the most suitable solution in this case will be to exclude these constructor-functions names from uglify's obfuscation list.
